IntroductionThe Installation Line Array (ILA) is a high performance line array system designed for the needs of Houses of Worship, Performing Arts facilities and a multitude of other venue types. The current ILA family is composed of the WL2082-i line array element, WL118-sw subwoofer, FB2082-i array frame, PB2082-i pull-back bar, EB2082-i extension bar, and GS115-sw ground stack kit.

Installation Line Arrays may be used in outdoor applications where the system is somewhat protected from the elements. The enclosure material is formulated with UV inhibitors, the grille is made of aluminum and the woofer cones are weather resistant.

WL2082-iThe WL2082-i line array element uses two high-power, neodymium magnet, 2" voice-coil, 8" low-frequency drivers in a two-and-a-half-way configura-tion. Both woofers produce low frequencies but only one covers the mid-range, resulting in far better horizontal directivity control in the crossover region. Excellent high-frequency output and clarity are provided by a pair of 1.75" voice coil, neodymium magnet compression drivers with titanium diaphragms. These drivers are mounted to QSC’s patented* multiple-aperture diffraction waveguide that provides an extremely wide horizontal cover-age of 140º. As a result, systems will rarely require side or center fill speakers and solid stereo imaging is preserved across the listening area.

The low-frequency capability of a WL2082-i array extends to 68 Hz (-10 dB); adequate for speech/vocal and acoustic music program material. For reinforcement of program material with more demanding low-frequency content, the WL118-sw companion subwoofer is available.

Introduction (continued)

WL118-swThe WL118-sw subwoofer extends the system’s low-frequency capability to 35 Hz. Its ceramic magnet, 4" voice coil, 18" transducer provides 850 watt continuous power handling capability.

Many users of line array systems have found that suspending the subwoofers with the array provides audible benefit. Additionally, many venues lack physical space for floor-mounted subs. For these reasons, the WL118-sw includes rigging hardware and, with selection of the appropriate rigging acces-sories, subwoofers may be flown at the top of or behind a WL2082-i array.

RiggingRigging the Installation Line Array is simple and flexible. Enclosures are bolted together with the provided M8 shoulder bolts or pinned together with optional quick-release ball-lock pins.

The FB2082-i array frame supports most flown array applications, and the EB2082-i extension bar supports suspension where the center of gravity is beyond the limits of the FB2082-i. Additionally, the EB2082-i is used for arrays where subwoofers are flown behind the main array. The PB2082-i pull-back bar is used for pulling back the bottom element of the array for aiming and stability or as the primary suspension component for certain small arrays.

Ground stacking is easily accomplished using the GS115-sw ground stack kit. The kit includes two ground stack rails which attach to the rigging straps under the WL118-sw. These rails provide added stability and allow for ground stacked arrays to be constructed.

Rigging the Installation Line ArrayRules for Suspension

Correct use of all suspension hardware and components is imperative in sound system rigging and deployment.•

Always calculate suspended loads before lifting to ensure suspension components and hardware are used within their respective load limits.•

Research local codes and regulations to fully understand the requirements for suspended loads in the venue in which the equipment is •to be suspended.

Use only shackle holes for suspension of array.•

Be absolutely certain of the integrity of any structural member intended to support suspended loads. Hidden structural members can have hidden •structural weakness.

Consult a Professional Mechanical or Structural Engineer licensed in the jurisdiction of the sound system installation to review, verify, and approve •all attachments to the building or structure.

Never assume anything• —owner or third-party supplied suspension attachment points may not be adequate for the loads to be suspended.

Employ the services of a Professional Rigger for hoisting, positioning, and attaching the equipment to the supporting structure.•

Always inspect all components (enclosures, suspension brackets, pins, frames, bolts, nuts, slings, shackles, etc.) for cracks, wear, deformation, •corrosion, missing, loose, or damaged parts that could reduce the strength of the assembly before lifting. Discard any worn, defective, or suspect parts and replace them with new appropriately load-rated parts.

Shock Loading

When a load is either moved or stopped, its static weight is magnified. Sudden movements can magnify the static weight several times. This magnification of static weight is termed “shock loading.” Shock loading poses a danger to equipment and workers. The effects of shock loading can be instantaneous, or they may remain undetected unless the equipment is visually damaged. Avoiding shock loading requires careful planning and knowledge of equipment, rigging, and lifting practices.

Shock loading of equipment and structures is usually confined to lifting and installation, but natural forces (winds, earthquakes) can impose shock loads several times the static load. This is why structures and suspension equipment must be capable of supporting several times the weight of the equipment suspended.

ILA Working Load Limits and Design Factors

The following table lists ILA suspension components and provides Working Load Limit data at various Design Factors. The tabulated Design Factors are for static loads only. The choice of which Design Factor to use will depend upon the jurisdiction and venue of installation, as well as the conditions of suspension. Dynamic conditions are determined by unknown, installation-specific factors and should be referred to a Licensed Structural Engineer for clarification before proceeding with any suspension of the equipment. The data presented is based upon the listed component weights:

Attaching WL2082-i to Array Frame (Figure 1)

Before beginning any installation, have your system designer calculate the proper splay angles using QSC’s EASE Focus (Array Calculator). All orientation of product is to be as viewed from the rear of the enclosure.

Attach the array frame to the suspension structure using a 3/4" (20 mm) screw pin anchor shackle and appropriate sling, cable, etc.

For arrays of four WL2082-i or less, assemble the cluster of WL2082-i on the ground using the included mating hardware. Ensure the notched rigging plate is on the right hand side (the system can only be installed one way. Note the QSC logo on the input plate will be right side up when the enclosure is oriented properly). During assembly, ensure your splay angles are as desired.

When constructing large arrays it is recommended to first assemble units of four enclosures and then assemble the final array by joining the four enclosure units to one another.

Attachment of one enclosure to another is accomplished by inserting the cap-head shoulder bolt with washer through the rigging plate attachment holes and appropriate splay angle selection holes in the mating rigging plates and threading the lock nut (nylock) on the inside edge of the plates. The bolt should be tightened snuggly to no more than 5 lb-ft of torque (6.8 N-m).

Attach the array frame to the top enclosure by inserting the cap-head shoulder bolt with washer through the appropriate mounting holes and threading the lock nut (nylock) on the inside edge of the plates. The bolt should be tightened snuggly to no more than 5 lb-ft (6.8 N-m) of torque.

NOTE: For some array configurations, use of the extension bar and/or pull-back may be required to achieve the required aiming angle.

Pull-Back Bar (Figure 2)

If using the pull-back bar, attach to the bottom enclosure at the bottom-most splay angle adjustment holes at the rear of the rigging plate by inserting the cap-head shoulder bolt through the mated pieces and threading the lock nut (nylock) on the inside edge of the plates. Use a 5/8" (16 mm) shackle to attach to the pull-back bar shackle hole located in the center of the main bar.

NOTE: All hardware/components must be rated for the expected loads as determined by the Professional Engineer responsible for suspension.

NOTE: A washer should not be used when attaching the pull-back bar. This will allow the pull-back bar to pivot freely.

Rigging the Installation Line Array (continued)Extension Bar (Figure 3)

The extension bar rigging plates can be moved, if required, by removing the two 7/8" mount-ing bolts, moving to the selected mounting location, and reattaching. Tightening torque is to be 100 lb-ft of torque (135.6 N-m) EASE Focus software’s center-of-gravity calculator will provide a suitable point (or two points) for desired down-tilt. Attach the array frame to the extension bar rigging plates by centering the array frame member between the extension bar rigging plates and bolting together using the supplied 7/8" bolts.

Attaching the WL118-sw to the Array Frame (Figure 4)

All orientation of product is to be as viewed from the rear of the enclosure. The QSC logo on the input plate will appear right side up when the enclosure is oriented properly.

Attach the array frame to the suspension structure using 3/4" (20 mm) shackle and appropriate sling, cable, etc.

For all four rigging straps: Using a 6 mm hex wrench, remove the upper and lower rigging strap retaining bolts and loosen the two bolts in between. Pull the inner and outer straps to their outermost position; pull the center strap to its outermost position, and align the retaining bolt holes with the threaded inserts of the enclosure. Re-install the outermost rigging strap retaining bolts and tighten all four bolts on each strap to 13 lb-ft (17.6 N-m).

Lower the array frame onto the enclosure, carefully aligning the rigging straps, and attach the top enclosure to the array frame by installing the ball-lock pins or M8 bolts. Before lifting, ensure the audio connection to the enclosures are correct and functioning (Figure 5).

NOTE: When attaching one WL118-sw to another WL118-sw, you must use the supplied ball-lock pins. This will allow for easier installation given the close

spacing between consecutive WL118-sw enclosures.

NOTE: When arraying two or more WL118-sw subwoofers, it is easiest to lay the enclosures on their backs, align and mate the rigging straps, and install the

ball-lock pins. When installing the ball-lock pins, ensure full insertion and locking action. (Figure 6)

Rigging the Installation Line Array (continued)Attaching the GS115-sw Ground Stack Rails to a WL118-sw (Figure 7)

For all four rigging straps: Using an 6 mm hex wrench, remove the upper and lower rigging strap retaining bolts and loosen the two bolts in between. Pull the inner and outer straps to their outermost position; pull the center strap to its outermost position, and align the retaining bolt holes with the threaded inserts of the enclosure. Re-install the outermost rigging strap retaining bolts and tighten all four bolts on each strap to 13 lb-ft (17.6 N-m).

Position a GS115-sw ground stack rail between the rigging straps on the right and one to the outside of the rigging straps on the left side of the loudspeaker.

Attach the rail to the rigging strap by inserting the cap-head shoulder bolt with washer through the mated components and threading the lock nut (nylock) on the inside edge of the assembly. The bolt should be tightened snuggly to no more than 5 lb-ft (6.8 N-m).

NOTE: GS115-sw must be attached to at least one WL118-sw for stability before any additional loudspeakers are attached. GS115-sw should never be attached

directly to a WL2082-i loudspeaker.

NOTE: GS115-sw is designed to accommodate up to two WL118-sw loudspeakers and up to six WL2082-i loudspeakers.

Attaching WL2082-i enclosures beneath WL118-sw enclosures (Figure 8)

For arrays of four WL2082-i loudspeakers or less, assemble the WL2082-i loudspeakers on the ground using the included mating hardware. Ensure the notched rigging plate is on the right hand side (the system can only be installed one way; the QSC logo on the input plate will appear right side up when the enclosure is oriented properly). During assembly, ensure your splay angles are as desired.

When constructing large arrays it is recommended to first assemble units of four enclosures and then assemble the final array by joining the four enclosure units to one another.

Attachment of one enclosure to another is accomplished by inserting the cap-head shoulder bolt with washer through the mated rigging plates and appropriate splay angle selection holes and threading the lock nut (nylock) on the inside edge of the plates. The bolt should be tightened snuggly to no more than 5 lb-ft (6.8 N-m).

Lower the array frame with subwoofer(s) onto the WL2082-i enclosure cluster and attach the top enclosure to subwoofer by inserting the cap-head shoulder bolt with washer through the mounting holes and threading the lock nut (nylock) on the inside edge of the plates and rigging straps.

NOTE: See Pull-Back Bar and Extension Bar sections on previous page for information regarding their use.

Rigging the Installation Line Array (continued)Attaching WL118-sw Behind WL2082-i Array Using EB2082-i (Figure 9)

It is sometimes necessary to suspend the subwoofers behind the main array. Extreme splay angles may result in physical interference with rear-flown subwoofers.

Attach both array frames to the extension bar rigging plates by centering the array frame member between the extension bar rigging plates and bolting together using the supplied 7/8" bolts. The extension bar rigging plates can be moved, if required, by removing the two 7/8" mounting bolts, moving to the selected mounting location, and reattaching. Tightening torque is to be 100 lb-ft (135.6 N-m). EASE-Focus software’s center-of-gravity calculator will provide a suitable point (or two points) for desired down-tilt.

The rear suspended WL118-sw subwoofer(s) may now be attached to the array frame; see “Attaching the WL118-sw to the Array Frame.”

The front suspended WL2082-i loudspeakers may now be attached to the array frame; see “Attaching WL2082-i to Array Frame.”

– Figure 9 –

– Figure 10 –

NOTE: When stacking loudspeakers for attachment to array frames using the extension bar, we recommend working with groups of 2 WL2082-i for each

WL118-sw. Start with no splay angle; this yields the same height for landing the extension bar. Adjust splay angle once the rig is lifted.

Suspending Four or Less WL2082-i Loudspeakers Using Two Pull-Back Bars (Figure 10)

NOTE: Do not suspend more than four WL2082-i loudspeakers from a PB2082-i pull-back bar! Do not use PB2082-i pull-back bar for suspending anything other

than 4 or less WL2082-i loudspeakers! Do not suspend the WL118-sw from the PB2082-i pull-back bar!

NOTE: A washer should not be used when attaching the pull-back bar. This will allow the pull-back bar to pivot freely.

Warning! Four (4) WL2082-i loudspeakers is the maximum allowable load (10:1 design factor) for the PB2082-i. Do not suspend more than four WL2082-i

loudspeakers from the PB2082-i.

Assemble the array of WL2082-i loudspeakers on the ground using the included mating hardware. Ensure the notched rigging plate is on the right hand side (the system can only be installed one way. Note the QSC logo on the input plate will appear right side up when the enclosure is oriented properly.

Attachment of one enclosure to another is accomplished by inserting the cap-head shoulder bolt with washer through the mated rigging plates and appropriate splay angle selection holes and threading the lock nut (nylock) on the inside edge of the plates. The bolt should be tightened snuggly to no more than 5 lb-ft of torque (6.8 N-m).

Attach one PB2082-i to the top enclosure’s front, top rigging plate attachment holes by inserting the cap-head shoulder bolts without washers through the mated pieces and threading the lock nut (nylock) on the inside edge of the plates. The bolts should be tightened snuggly to no more than 5 lb-ft of torque. See (Figure 1) for assembly detail. Use a 5/8" (16 mm) screw pin anchor shackle to attach to the pull-back bar shackle hole located in the center of the pull-back bar for lifting.

Attach the second PB2082-i to the bottom enclosure at the bottom-most splay angle adjustment holes at the rear of the rigging plate by inserting the cap-head shoulder bolts without washers through the mated pieces and threading the lock nut (nylock) on the inside edge of the plates. The bolts should be tightened snuggly to no more than 5 lb-ft (6.8 N-m) of torque. Use a 5/8" (16 mm) screw pin anchor shackle to attach to the pull-back bar shackle hole located in the center of the main bar for pulling back.

WL2082-i Controls and ConnectionsMODE Selection Switch (Figure 11)

BI AMP: When set to BI AMP, an internal shading network removes the mid frequencies from one of the low-frequency drivers. The BI AMP HORIZONTAL SHADING switch will select which transducer is shaded.

TRI AMP: Shading network is NOT applied (shading must be provided by upstream signal processing). The BI AMP HORIZONTAL SHADING selector switch is not functional in tri-amp mode. Connect to the Speakon as shown for tri-amp (Table 2).

BI AMP MODE HORIZONTAL SHADING

Selection Switch (Figure 12)

The BI AMP MODE HORIZONTAL SHADING selection switch is only functional in bi-amp mode. This switch determines which low-frequency transducer receives only low-frequency program material (shading). The unshaded transducer receives low- and mid-frequency program material. This allows switch position selection for use as either “house left” or “house right,” without the need to flip boxes.

NOTE: LEFT and RIGHT markings on the BI AMP HORIZONTAL SHADING SWITCH apply to the enclosure as viewed from the rear (i.e. looking at the Input Plate with

the text properly oriented).

LEFT: Use this setting to shade out mid frequencies in the left (as viewed from behind the arrays, looking toward the audience).

RIGHT: Use this setting to shade out mid frequencies in the right (as viewed from behind the arrays, looking toward the audience).
